To provide a control device for a work machine, the work machine, and a control method for the work machine, which can stably control motion of an actuator even when a hydraulic device exhibits nonlinear behavior characteristics.SOLUTION: A controller 101 performs a control system process including a control model set to cause a variable capacity motor 121 to execute a prescribed operation in response to an operation instruction signal output from a derricking lever 111 and a reverse conversion process for canceling nonlinear characteristics included in a hydraulic circuit mechanism H in a linking manner, thereby generating a flowrate instruction signal for entry to a flowrate adjustment unit M in response to the operation instruction signal.SELECTED DRAWING: Figure 2

    【課題】油圧機器が非線形の挙動特性を示す場合であっても、アクチュエータの動きを安定して制御することが作業機械の制御装置および作業機械、作業機械の制御方法を提供する。【解決手段】コントローラ101は、起伏レバー111から出力される操作指令信号に応じた所定の動作を可変容量モータ121に実行させるように設定された制御モデルを含む制御系処理と、油圧回路機構Hに含まれる非線形特性を相殺するための逆変換処理とを連結して処理することで、流量調整部Mに入力するための流量指令信号を前記操作指令信号に応じて生成する。【選択図】図2
